The Sunnyvale chip designer just unveiled a new Accelerated Processing Unit (APU) designed for performance tablets and small form factor (SFF) PCs, the AMD Z-60. It's a low power chip that promises all-day battery life along with "stunning graphics" and support for the latest Windows 8 applications, AMD says.
